In the Addressbook example, any entry whose name doesn't start with a letter will not appear in any of the categories, but it will still exist. These entries would make the "There are currently no contacts in your address book" page disappear even when no entries could be found in the categories. Check if a new entry has a name that doesn't start with a letter, and if so, don't add it as a contact. Also, notify user that names must start with a letter when this happens.
